The specific embodiment
Such as Fig. 2 and shown in Figure 4, the pulling plug formula magnetic key operated lock of spin of the present utility model braking comprises that the flanged pulling plug 21 in top of the vertical protrusion that is fixed on door one side, the upper shed that is fixed on an opposite side can insert the sleeve 22 of pulling plug 21, fill in 23 in the relative sleeve 22 axially movable sleeves of sleeve 22 interior energy, be nested with locating snap ring 24 outside sleeve 22, can snap into pull bar 26 on the outer wall of locating snap ring 24 filling in the revolving part 25 that rotates under 23 the effect and the end other end that links to each other with solenoid axle 27 between locating snap ring 24 and the sleeve 22 in sleeve.The mechanism in the aperture that having on sleeve 22 and the locating snap ring 24 works in coordination regulates these sleeve 22 a part of internal cavities, this mechanism comprises a plurality of holes 221 that have on sleeve 22 sidewalls and the ball of placing on the one hand in each hole 221, the side wall inner surfaces at locating snap ring 24 forms large aperture part and the small-bore part that distributes along inner ring on the other hand.Revolving part 25 links to each other with locating snap ring 24 also can drive the aperture of locating snap ring 24 rotating regulating sleeve 22 a part of internal cavities.
In this embodiment, thereby sleeve 22 is fixed on the underframe 201 with screw fit by the screw 222 of opening in its bottom, and underframe 201 is fixed on the doorframe.The below of placing a plurality of holes 221 of ball on sleeve 22 sidewalls is provided with axially extended fluting 223.
The two ends that connect respectively torsion spring 241 are connected in the bottom of locating snap ring 24 with underframe, the effect of torsion spring 241 makes locating snap ring 24 remain on the large aperture part of its inwall in the face of the hole 221 on sleeve 22 sidewalls and the state of ball.Small-bore part on locating snap ring 24 inwalls is radially inwardly protruded fin in this embodiment, when locating snap ring 24 rotates to fin on its inwall in the face of the state of the hole 221 on sleeve 22 sidewalls and ball under the drive of revolving part 25, fin radially shrinks ball 221 in sleeve 22, ball 221 is embraced the termination flange of pulling plug 21, thereby reaches the effect of locking a door.The sidewall external surface of locating snap ring 24 also is provided with the draw-in groove 242 that matches with the free-ended structure of pull bar 26.
The slope is formed on the top of revolving part 25, when plug 23 effects that overcome spring 232 are moved to sleeve 22 bottoms in the sleeve, bearing pin 231 in the sleeve on the plug 23 sidewall external surfaces is pressed the top of revolving part 25 downwards and is slided to the end, slope along the slope at revolving part 25 tops, make revolving part 25 drive locating snap ring 24 and overcome the effect of torsion spring 241 around sleeve 22 rotations, thereby be rotatablely moving of revolving part 25 with plug 23 axial linear conversion of motion in the sleeve, as shown in Figure 3.Preferably, the quantity of the bearing pin 231 in the quantity on the slope that revolving part 25 tops form and the sleeve on the plug 23 sidewall external surfaces is identical, and the sloping end on a slope connects the slope on next slope and pushes up.
Preferably, also between locating snap ring 24 and the sleeve 22, revolving part 25 above bearing 28 is set, bearing 28 inner rings are installed on the sleeve 22, outer ring and locating snap ring 24 closely cooperate, as locating snap ring 24 bearing around sleeve 22 rotations.
The free end of pull bar 26 forms the projection in the draw-in groove 242 that can snap on locating snap ring 24 outer walls, when small-bore part that locating snap ring 24 rotates to its inwall during in the face of the state of the hole on sleeve 22 sidewalls and ball, draw-in groove 242 on locating snap ring 24 outer walls arrives from the nearest position of pull bar 26 free-ended projections, at this moment solenoidal axle 27 drives the drive end of pull bar 26, the free-ended projection that drives pull bar 26 snaps in the draw-in groove 242 of locating snap ring 24 outer walls, so that locating snap ring 24 maintains static, as shown in Figure 5.Preferably, pull bar 26 also has an end to be installed on the underframe 201 by rotating shaft 261.
In the preferred embodiment of the pulling plug formula magnetic key operated lock of spin of the present utility model braking, this lock also comprises the top cover 202 that covers on the underframe 201, so that all lock assemblies of a side relative with pulling plug 21 all are enclosed in top cover 202 and underframe 201 inside.
Below, take outage lock, the switch on operating principle of the normally closed pattern of the unblanking pulling plug formula magnetic key operated lock of spin braking of the present utility model as example illustrates.
The pulling plug formula magnetic key operated lock that Fig. 2 and Fig. 6 illustrate spin of the present utility model braking is in opening, and at this moment, because the effect of torsion spring 241, locating snap ring 24 remains on large aperture part on its inwall in the face of the hole 221 on sleeve 22 sidewalls and the state of ball.When pulling plug 21 inserts vertically from the upper shed of sleeve 22, the top of pulling plug 21 promotes to fill in the sleeve 23 effects that overcome spring 232 and moves to sleeve 22 bottoms, being arranged in the sleeve bearing pin 231 on the plug 23 sidewall external surfaces is pressed in revolving part 10 tops and continues and move to sleeve 22 bottoms, bearing pin 231 slides to the end, slope along the slope at revolving part 25 tops simultaneously, thereby driven rotary part 25 is around sleeve 22 rotations, revolving part 25 drives effect and its synchronous rotary that locating snap rings 24 overcome torsion spring 241, until plug 23 stopping of 223 terminal points or sleeve 22 bottoms that be subject to slotting on sleeve 22 sidewalls in the sleeve.At this moment locating snap ring 24 rotates to small-bore part on its inwall in the face of the hole 221 on sleeve 22 sidewalls and the state of ball, small-bore part on locating snap ring 24 inwalls is radially shunk ball in sleeve 22, ball is embraced the termination flange of pulling plug 21, and simultaneously the draw-in groove on the locating snap ring 24 sidewall external surfaces has also arrived the position nearest apart from pull bar 26.The axle 27 of the helix tube of outage snaps in pushing drawing rod 26 free-ended projections in the draw-in groove 242 of locating snap ring 24 outer walls, locating snap ring 24 is maintained static realize locking, such as Fig. 3 and shown in Figure 5.
After the energising, the axle 27 of helix tube will spur the draw-in groove 242 that pull bar 26 free-ended projections are left locating snap ring 24 sidewall external surfaces, and locating snap ring 24 is returned to original position under the effect of torsion spring 241, realize unblanking.
Certainly, the pulling plug formula magnetic key operated lock of spin braking of the present utility model is also easily realized the normal on-mode that outage is unblanked, switched on and lock, as long as the position of drive end on the pull bar 26 with an end place that links to each other with rotating shaft 261 slightly made an amendment.
